Best Water Leak Detector for Range
YoLink was the first to bring the advanced technology of LoRa® to the smart home market. Our water leak detectors offer the longest receiving range in the market of up to 1/4 mile range.
Superior Battery Life
Save your time and money; while other leak detectors have a battery life lasting up to 1 or 2 years before they need to be replaced, YoLink’s low-power protocol allows for long range yet low-power smart water leak detectors, giving 5+ years of battery life!
IP67 WaterProof Rating
It may come as a surprise but many water leak detectors are not waterproof! The WLS1 is waterproof with a certified IP67 rating, which offers more protection than unrated or IP65/IP66-Rated products that are ‘water-resistant’. Our rating allows you peace of mind that you can reuse your sensor even if leaks happen.

Let customers speak for us
YoLink Smart Pool Floating Thermometer, 1/4 Mile Range, 5+ Years Battery Life, Emails, Text, App Alerts, Alexa, IFTTT. Pool, Hot Tub, Fish Tank. Hub Required!
I've deployed about 20 of these in various sites, all are working fine. Very comforting to know if water is leaking - we had two disasters in the last two years.
Installation and setup were painless. Got to give yolink credit for making it so easy to set up their devices. I own several water detection devices and have been very happy with them. I plan on trying out the motion sensors
Installed three X3 Smart Temperature & Humidity Sensors in two refrigerators and a freezer, one inside the house and two in the garage. Set up couldn't have been easier; open the Yolink app, click the 'add device' button, scan the QR code on the back of the sensor and it's set up, ready to edit the name and room as you see fit and set up alerts for hi/low temperature and humidity. The data reporting in the app works very well, allowing a variety of options to see the data over a selected date/time range, etc.
And, most importantly of course, Yolink's wireless technology works through the metal walls of refrigerators and freezers as claimed.
Great lock, great price and works perfectly :) I had the lock configured and set up before my installer was done putting in the strike plate. The ability to unlock with a fingerprint, FOB, passcode and key make this a fantastic lock. Best value on the market. Do you think I’m a fan of Yolink products? You bet. Hands down, one of the best smart locks I’ve come across.
Perfect For Pool Temp Monitoring! Works great! Easy to set up and just popped it into my pool and voila!
Despite having good results with Yolink’s door monitors and Alexa, there’s no evidence of connections between the Yolink deadbolt and Alexa. The PIN function works well and considering the price it’s a mediocre deal.
So Far very good!
Easy/intuitive setup. Immediately records pool water temps and provides me with more confidence with temps than my former ancient glass pool thermometer. And I don’t even have to leave my workdesk to see if the pool temp is ready for my swim workout. Outstanding technology!
Was using a Yolink thermometer hanging in pool before this. It has worked flawlessly for over three years! Put this in place and expect nothing less. Yolink is great!
Easy to setup and love the fact it notification even when you're away
It may not be the nicest looking outlet, but it works great - used in an outdoor control scenario and it works great when correctly enclosed - does not take extra space vs add on controllers)
Excellent value
